14-piece machine tap set HSS 7 machine taps M DIN 371/376 Form B with spiral point M 3 - M 4 - M 5 - M 6 - M 8 - M 10 - M 12 + 7 ULTIMATECUT twist drills DIN 338 Type FLOWSTEP® Ø 2.5 - 3.3 - 4.2 - 5.0 - 6.8 - 8.5 - 10.2 mm Machine taps made of high-performance high-speed steel. For through-holes and blind holes in unalloyed steels up to 800 N/mm² strength. The thread is cut in a single pass. High-speed steel, primarily known as HSS, refers to a group of alloyed tool steels with up to 2.06% carbon content and up to 30% alloying elements such as tungsten, molybdenum, vanadium, cobalt, nickel, and titanium. HSS materials are characterized by high hardness, wear resistance, and hot hardness up to 600°C. HSS tools are more resistant to impacts and vibrations, which can quickly lead to fractures in harder cutting materials.
